"In my personal struggle, you see me not changing and not giving up on this dream that I've had my whole life," Perry told MTV News.

"Hopefully people are inspired by that," she continued. "You don't always see me with all the gorgeous lighting and make-up on and all that. I think it's fine.

"Hollywood is so fake and people need to realize that people are just people, and you, too, don't need to be born into something or have money or have whatever product someone is hawking on you," she explained. "Find out what your gift is and nurture it."
